BACKGROUND Carboplatin is an analogue of cisplatin with less nonhematologic toxicity and a similar spectrum of antineoplastic activity. Although cisplatin has not been found to be an active agent against leukemia, carboplatin‐induced complete remissions have been observed in adults with acute myelogenous leukemia (AML), and antileukemic activity has been observed in a Phase I trial involving children with acute lymphoblastic leukemia (ALL) and AML. Therefore, a pediatric Phase II study was undertaken to determine the degree of activity of carboplatin in childhood ALL and AML. METHODS Between October 1991 and November 1994, the Children's Cancer Group conducted a Phase II study of carboplatin given by 5‐day continuous intravenous infusion to children with acute leukemia recurring in bone marrow. RESULTS Minimal antileukemic activity was demonstrated in patients with ALL and AML. One of 21 eligible patients with ALL achieved a partial response. Of 23 eligible patients with AML, including 1 patient with chronic myelogenous leukemia in blast crisis, 1 had hypocellular M1 bone marrow with a platelet count of 15,000/mm 3 , and 2 achieved partial responses. Nonhematologic toxicities, which were infrequent, included mild hepatic and renal dysfunction. CONCLUSIONS In this pediatric Phase II trial of carboplatin as a treatment for acute leukemia, minimal activity was demonstrated in patients with ALL and AML recurring in bone marrow. Further evaluation of carboplatin as a treatment for childhood leukemia, using the dose schedule of 216 mg/m 2 /day given by 5‐day continuous intravenous infusion, does not appear warranted.
